AI Underwater Video

An AI underwater video turns a swim into a slow dream: hair fanning out like ink, bubbles climbing past the lens, sunlight breaking through the surface in long rays. Start from a photo taken in clear water, or one of an adult who agreed, describe one move and one depth, and Sirena renders a vertical 5, 10 or 30-second clip. Soft, 18+ only and never explicit.

VERTICAL 9:16NATIVE AUDIOMP4

New · 16 models · 8 scenes

Ready-to-shoot scenes. One tap, they let loose.

A kiss in the club bathroom, a hand that wanders in the taxi at 4 a.m., a shower for two after the party… Pick a scene: the models and the full prompt drop straight into the studio. Tweak it, or let them play it exactly as written.

01
Club bathroom
Duo · Kiara & Lena
@Image 1 and @Image 2 in tight party dresses, one black with thin straps, the other silver and very short, in a nightclub bathroom: cracked white tiles, mirror smudged with fingerprints, paper on the floor, a purple neon light flickering and buzzing, bass thumping behind the door, a toilet flushing in the distance. @Image 2 holds the phone at arm's length, the frame tilts, she laughs: "Okay okay, we're filming this." @Image 1, leaning on the sink, bites her lip and grabs @Image 2 by the back of the neck: "Come here." Kiss with tongue, slow then more urgent, hands in the hair then on the butt through the dress, @Image 1's strap slips off her shoulder and uncovers a breast, she doesn't pull it back up. Lipstick smeared on both mouths, short breath, @Image 2 looks into the lens: "We're so bad," and they burst out laughing, the phone almost falls, reframes on the ceiling, cut.
02
VIP table twerk
Solo · Sara
@Image 1 in a black Brazilian thong and a sequined crop top pulled up above her navel, high heels, at a VIP table: red velvet booth, low table covered in bottles, sweating ice bucket, sparklers crackling on a bottle, white strobe and green lasers, smoke. Filmed by a friend slumped on the booth who shouts over the music: "Go on, show them!" @Image 1 turns her back to the camera, spreads her legs, hands on her knees, arches her back and twerks to the beat, butt bouncing, thong sinking in, sweat in the small of her back. She turns around laughing hard, hair stuck to her forehead, grabs a bottle by the neck and raises it to the lens: "To tonight, bitches!", drinks, chokes, laughs. Flash from another phone, a bouncer passes by blurred, the friend screams with laughter, the image shakes everywhere.
03
Taxi home
Duo · Mia & Chloe
@Image 1 and @Image 2 in the back of a taxi at 4 a.m., worn black leather seat, an air-freshener tree hanging from the mirror, shop signs and red lights sliding across their faces in blurry patches, the indicator ticking, radio turned low, the driver blurred from behind. @Image 1 holds the phone low, the frame sometimes cuts off their heads. @Image 2, shoes in hand, rests her head on her shoulder: "Best night of my life, I swear." @Image 1 whispers: "Shh, he can hear us," nodding toward the driver, they giggle. @Image 2 lifts her head, their eyes meet, kiss with tongue, slow, @Image 1's hand slides under @Image 2's dress out of frame, @Image 2 closes her eyes and holds her breath, then @Image 1 goes "Shhh" to the lens with a smile, the phone reflected in the window, a pothole shakes them, they laugh.
04
Afterparty in bed
Solo · Yasmine
@Image 1 in a white thong, topless, lying on a hotel bed at 5 a.m.: crumpled white sheets, pillow half on the floor, dress in a ball on the floor, heels knocked over, a water bottle on the nightstand, only the bedside lamp on, yellow light, blind half open on a sky turning blue, distant music through the wall. Running mascara, glitter stuck to her cheek. She films herself at arm's length, hoarse voice: "It's five a.m. and I am not even tired," yawns right in the middle, laughs at her own yawn. She rolls onto her stomach, arches her back, the thong rides up her hips, her butt lifts, she looks over her shoulder: "Okay, maybe a little," blows a kiss to the camera, buries her face in the pillow, says a muffled "Good night", and the phone drops onto the sheet, blurry shot of the lamp.
05
Dancefloor
Duo · Mei & Bianca
@Image 1 in a tight black mini dress with no bra, nipples visible through the fabric, in the middle of a packed dancefloor: red lights, smoke, a disco ball, distorted music crushing the mic, bass shaking the image, strangers' shoulders and arms crossing the frame, a spilled glass on the floor. @Image 2 films very close, at arm's length, the frame cropped and tilted. @Image 1 shouts into the lens: "I can't hear you!" laughing, @Image 2 grabs her by the waist, they dance pressed together, hip to hip, the dress rides up her thighs and @Image 1 lets it, hair stuck down, skin shiny with sweat. Kiss with tongue in the middle of the crowd, a stranger bumps into them, they laugh into the kiss without letting go, @Image 2 shouts "Oops!" and a phone flash blinds them.
06
Shower after the party
Duo · Natalia & Rosa
@Image 1 and @Image 2 in the same shower after coming home from the club: narrow stall with blackened grout, patterned plastic curtain, shampoo bottles on the floor, harsh ceiling light, steam, the sound of water drumming on the tray. @Image 1 holds the phone out of the spray, fog on the lens, makeup running in black streaks, bare breasts, hair slicked down. @Image 2 steps under the water and lets out a little scream: "Oh my god, it's freezing!" @Image 1 laughs: "Come here, I'll warm you up," pulls her close, chest to chest, they kiss under the water, hands on backs and hips, framed at shoulders and faces, water splashes the lens and blurs everything, @Image 1 wipes the lens with her thumb laughing, her fingerprint shows, @Image 2 says "You're getting it wet" and they laugh even harder.
07
Rooftop
Solo · Isla
@Image 1 in a black thong and heels on a rooftop at 3 a.m.: gravel underfoot, cold metal railing, lit-up towers behind, a red sign blinking on a facade, wind whistling in the mic, a siren in the distance. Filmed by a friend whose voice shakes with laughter: "You're not gonna do it!" @Image 1, still wearing a sequined top, answers "Watch me," pulls it off in one move and spins it above her head, topless, goosebumps on her arms, nipples hard from the cold, she shouts at the city "I love this city!", turns around and twerks against the railing laughing hard, a champagne bottle in her hand foaming over her fingers, the friend screams "Oh my god, oh my god!", a streetlight overexposes the image, then it plunges into darkness as she turns.
08
Club cloakroom
Solo · Tina
@Image 1 in the dark cloakroom of a nightclub: racks loaded with jackets and coats, numbered tickets, an empty counter, red light from the corridor filtering through the half-open door, muffled bass, distant voices. Selfie video held at arm's length, strapless dress pulled down to her waist, topless, marks from the dress on her skin. She whispers to the lens with a half smile: "Quick, before someone comes in." She arches against the wall of jackets, slowly caresses her breasts while staring at the camera, visible breathing, bites her lip, her other hand slides down her stomach and out of frame. A door slams in the corridor, she jumps, yanks her dress back up and bursts out laughing, hand over her mouth: "Oh my god, no!", the phone tilts sideways and the video cuts.

Why underwater footage looks so unreal

Water bends light and slows every movement. Hair lifts and drifts, fabric floats a little behind the body, and the sun arrives from above in soft shafts. Those three things are the whole look, and a model renders them well when the photo is clear and the move is slow.

The model takes its scene from your photo. A shot just under the surface keeps the light and the ripple pattern. Name the depth in words, because “near the surface” and “on the floor” give very different clips. For skin that catches the light, try the AI wet look video page.

Real clips, ordinary photos

These are real studio clips made from ordinary photos, shown for their movement and light. They are not demos of an underwater scene like yours.

Slow lap — Reference photo — **Slow lap**A calm stroke and a turn at the wall. The camera holds still while the body moves.

From photo to underwater clip in five steps

Seedance 2.5 renders every clip in one flow. Depth matters most:

Pick a clear reference
Calm, clear water and a readable face or body. Murky water carries over into the clip.
Add a second reference if needed
One more adult or a cleaner background. Up to 12 references, JPG, PNG or WEBP, 10 MB each.
Name the depth
Surface, mid-depth or near the floor, and where the light comes from.
Choose length and quality
Pick 5, 10 or 30 seconds, then Medium 480p, High 720p or Ultra High 1080p.
Render and check
Sirena returns a vertical 9:16 MP4 with native ambient audio. Check the hair and the light.

Four depths, four cameras

Depth decides the mood. Pair each one with its camera:

Depth	Move for the person	Camera
Surface split	Half above the water, breathing out bubbles	Locked camera, waterline level
Mid-depth glide	Drifts forward, arms loose, hair spreading	Slow push-in from the side
Floor look-up	Looks up toward the light, one hand reaching	Low angle rising slowly
Light from above	Turns in a shaft of sun, eyes half closed	Slow orbit with the light behind

Underwater motion is slow by nature. Keep the clip to five or ten seconds and one depth change at most.

Underwater prompts you can load

Your clear-water photo is @Image 1. Each prompt names the depth, the light and one slow action.

Hair in the blue
@Image 1 drifts in clear blue water, her hair spreading out around her face like ink, eyes half closed, slow push-in from the side, shafts of sunlight from the surface, muffled water hush and a few rising bubbles.
Surface split
@Image 1 floats just under the surface, half above the waterline, breathes out a stream of small bubbles and looks up toward the camera, locked camera, bright noon light, soft splashing above.
Look up to the light
@Image 1 hangs in the water near the pool floor, looks up toward the surface and reaches one hand toward the light, slow rising low-angle shot, rays of sun across the frame, deep muffled sound.
Fabric in the current
@Image 1 sinks slowly through the water in a loose light fabric that lifts around her body, she turns her head toward the camera, slow orbit with the sun behind, gentle bubbles and a low underwater hum.

Clear water and soft light: a checklist

Underwater clips fail in their own ways. Check before you render:

Clear water in the photo. Murky water turns the clip into fog.
A light source you can name, usually the sun from above.
Hair and fabric already lifting. The model learns the drift from it.
Only adults who agreed in frame.
One slow action and one depth.

No underwater photo? Upload a photo of you as @Image 1 and a clear-water image you have rights to as @Image 2. Expect less faithful water.

Underwater clip prices

Priced by length and quality only, never by the depth or the pool:

EUR per clip, whatever the water
Length	Medium · 480p	High · 720p	Ultra High · 1080p
5 seconds	$5.19	$6.49	$15.59
10 seconds	$6.49	$11.69	$31.19
30 seconds	$15.59	$32.49	$92.29

Soft underwater light holds up well in High 720p, at $11.69 for a ten-second clip.
For a detailed rising shot through sunlit water, Ultra High 1080p at $31.19.
Pay per video by card or with piments. Confirmed provider failures restore piments for piment purchases or trigger a refund of the original single-video card payment.

Under the surface: glamorous, consensual, never explicit

The terms of use apply to every underwater clip.

Welcome below the surface

Your own photos from a pool, a lake or a clear sea
Adult friends or partners who agreed, solo or together
Swimwear, light fabrics, sunglasses left on the deck
Water, light, bubbles, slow motion and long looks to camera

Stay on the surface

Explicit sexual content, nudity or sexual acts — such requests can be refused by the video provider’s checks
Anyone under 18 or who looks it
Celebrities, influencers or strangers who did not agree
Removing someone’s clothing, face swaps, or clips that pretend someone was somewhere they were not

Anyone recognizable in the water must be an adult who agreed to this clip, confirmed by you before each render.

AI underwater video questions

Do I need a photo taken underwater?

It helps most, because the light and the water colour come with it. A pool deck photo also works, with the water as background.

Why does the water look like fog?

The reference was murky or the light was flat. Start from a clear photo and name a light source.

Can the camera rise toward the surface?

Yes. “Slow low-angle rise toward the light” works well. Keep it gentle.

Does the clip have underwater sound?

Yes: a muffled hush, bubbles and a faint hum. No music is added.

Can I post it as a Reel?

It is a vertical 9:16 MP4, ready for Reels and Stories. Label it as AI where the platform asks.
